Looking for irda - serial module

Hello, i am developing a project which needs to send data from one arduino comaptible board to another using infrared.

I am planning to use irda, but seems few projects use this nowadays, i found few ttl-irda boards, and really expensive 20€+, but the module costs ~2€, so, i ask wether anybody knows where to buy it at a reasonable price.

Also, i am planning to custom build a board at easyEda using: https://www.vishay.com/docs/81288/tfdu4101.pdf

But i have doubts on the scematic...

Thanks a lot :slight_smile:

This is 25khz filtered analog sensor, i am looking for a complete serial transceiver.
